  • There was a book a while back called Guns, Germs, and Steel that delves into this topic.

    The root cause, as I understand it, is that Europe is on a continent oriented east-west instead of north-south. And Europe in particular is on the part of that continent that has a lot of easy access to the sea.

    East-west orientation allows you to transplant plants and animals long distances and keep them at roughly the same latitudes, which means roughly the same climate. That is a big boon for spreading “civilized” agriculture, which is what creates surplus of labor, which creates non food jobs that advance technology.

    Among the common 5-7 domesticated food animals people eat today, all but one or two were domesticated in Mesopotamia, but then spread all over Europe.

    Access to the sea is the other component that turns tech advantage into colonialism, because it gives the transportation. Even today, China and Russia are great powers, but they are forced to be continental powers instead of maritime powers, because nearly all of their coast lines are hemmed in by narrow seas that are easy to blockade.

    There are, of course, a bunch of other factors I’m not even thinking about and competing opinions. But I don’t for one second think that any of this has anything to do with European “innate intelligence” or skin color.




  • The deal with Utah is it’s actually only 40% Mormon. And when you have a bunch a kids growing up in the Mormon church, a decently large number of them will crash out. And when they crash out, they tend to crash out pretty hard.

    So Utah has large communities for various countercultures and alternative lifestyles. You can visit a random business, and often find both types working together side by side. And it is usually quite obvious which is which from external signs.




  • I agree that it’s lazy copy editing. “Allegedly” is used in the newspaper business as a magic “get out of any libel suit” word.

    However, I don’t think it’s necessarily safe for the news flat report that Trump “did” the thing. They can report on what Carroll says he did (those are the allegations). And they can report that a jury determined it’s more likely than not that he did the thing.

    This is a situation where explaining it correctly requires several more words than the editors wanted to spare.

    To condemn NASA a little bit further: NASA engineering also insisted that Sally Ride absolutely had to have a flight makeup kit. They went to the trouble to design one and make sure everything would work in zero-g. It went up and came back down completely unopened.








  • The vacuum is only ≈3K, or -270.15° C, but a vacuum is not particularly receptive to heat dispersal.

    This is true for all of the black parts of the sky.

    It is not true for that big yellow ball that shines on the space station half of the time. That big yellow ball is as bright and hot as a hot desert day on the surface. Daylight can raise the vacuum temp up to +250 or +300 C. And it also means that the night time temps don’t cool down all the way to 3K.

    So the ISS is continuously exposed to these thermal cycles on the outside. As a heat load these should dwarf any marginal heat loads introduced by whatever recreational drugs. And the station has to have radiator capacity handle it all plus margin. Remember, too, that the ISS crew also has to do hard exercise 2 hours per day.


  • If we’re using NASA as a reference Suni Williams and Butch Wilmore were in space for 286 days instead of a planned week long mission.

    They did get resupplied with additional clothing and personal effects after a few weeks.

    Coincidentally, there is no laundry or shower on the international space station.
